高温石墨的近红外辐射及实时温度测量

Near-infrared Radiation of Graphite at High Temperature and Real time Temperature Measurement

本文讨论了高纯石墨表面单色辐射率ελ,T（λ=0.9/zm）在1000℃-3000℃范围内的变化,以及ελ,T对温度测量的影响。实时测温系统由红外辐射探测装置、光纤传导、微机数据采集、显示等部分组成。在石墨炉原子吸收光谱分析应用中。

A discussion is given of the variation of pure graphite emissivity ελ,T（λ=0.9μm）in the range 1000℃ to 3000℃. In graphite furnace atomic absorption analysis, the real time photoelectric temperature meter can be used as temperature indicator and controller.
